RAILROAD-CAR STRUCTURE.

SPECIFICATION forming part of Letters Patent Ne. 511,588, dated December 2c, 189s.

Application tiled March 17. 1893. Serial No. 466,505. (No model.)

To a/ZZ whom, t may concern:

Be it known that we, FRANCIS J. COLE and EDWARD W. GRIEVES, citizens of the United States, and residents of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Railroad-Car Structures, of which the following is a specification.

Our invention relates to the construction of a freight car for use on railroads and has for its object to strengthen the frame-Work ot the structure in such a manner as to resist the shock of impact while coupling.

In the drawings Figure 1 is a vertical section of the car frame; Fig. 2, a plan of a part of the car frame; Fig. 3, an end elevation of part of same; Fig. 4, a side elevation of abutting block; Fig. 5, a top elevation of abutting block; Fig. 6, an end elevation of abutting block. Fig. 7 is a vertical longitudinal section of modiiied structure.

In the drawings 1-1 are the draw-bar timbers of the car; 2 the coupling head and bumper; 3 the bumper spring; 4 the bumper follower plate upon which the bumper spring rests.

5 is a'lling block shown in detail in Figs. 4, 5 and 6. The form shown in Figs. 4,5 and 6 is the one' shown in Fig. 7; that shown in Fig. 1 diders from it only in not beingcut entirely through at the end, that is to say, the

slots 1S and 19 in which the stem20 of the clined notch 23 and extending across the rear ends of both draw-bar timbers and block 5.

7-7 are two truss rods which pass through the plate or washer 6, through the grooves 12-12 in the sides of the block 5 (Fig. 4) through slots in the sides of the central timber 10, and through the end sill 9, and Washer 8. Upon its extremity a nut'is screwed which bears upon the washer 8.

rods 7-7.

The central timber 10 is not usually used in constructing freight cars of this class.y It stands between the timbers 11-11, to which it is bolted by a series of transverse bolts. The end of the timber 10 abuts'against the end sill 9 in its center and between the truss The underside of the timber 10 is notched at 14-l4, Fig. 1, andthe block 5 which extends slightly above the draw-bar timbers l-lrtits into the forward end of said notch. 13 is across-brace timber which stands immediately behind the block 5 and the drawbar timbers 1-1 and against which they abut; it fits on its upper edge into the other end of the notch 14, and together with the block 5 occupies said notch. In Fig. 7 the structure is slightly different, the notch 15-15 being deeper than 14-14, and being occupied ventirely by the block 5, while beyond it there is another notch 16 which is occupied by the cross timber 13. Fig. 7 also shows a slightly different arrangement of end-sill timbers.

It -will be readily seen that when a blow is struck upon thecoupling, the shock will be received by the bar 2, and imparted to the plate 4, and draw-bar timbers 1-1 and the block 5, both of which abut uponV the cross timber 13, which is notched into the timber 10. Timber 10 being bolted by a series of So horizontal bolts to the frame timbers of the car-body, the strain put upon the draw-bar timbers 1-1 and the block 5 will also be imparted to the truss rods 7 7, through the plate 6, and by said belts to the end sill 9, and to the frame of the car. It will thus be seen that\ all shocks upon the couplings will beequally distributed throughout the car frame, and the maximum strength secured.

Having thus described our invention, what 9o below the central timber, the block and crossbar timber entering the notch or notches of the central timber.

In a car frame the combination of draw 5 bar timbers, a straight truss rod in a single piece secured to the rear of the cross bar timbers at one end, the end-sill of the car to which the truss rod is secured at the otherend, and a central frame timber for the car bearing L o against theend-sill, substantiallyas described.
